The nurse is teaching the adolescent patient Duchenne muscular dystrophy about the disease. What will the nurse include?

A. Institute seizure precautions is incorrect because Duchenne muscular dystrophy (DMD) primarily affects muscle strength and function, not neurological activity or seizure risk. Seizure precautions are not routinely required unless the patient has a separate seizure disorder. B. Maintain a high-calorie diet is incorrect. While nutrition is important, DMD patients are often at risk for obesity due to decreased mobility, so a balanced diet rather than a high-calorie diet is recommended to maintain healthy weight and prevent added strain on weakened muscles. C. Perform range of motion exercises is correct. Regular range of motion (ROM) exercises help maintain joint flexibility, prevent contractures, and preserve functional mobility as long as possible. Physical therapy is a cornerstone of DMD care, aiming to maximize independence and quality of life. D. Restrict the use of large muscles is incorrect because immobilizing or avoiding muscle use can accelerate muscle atrophy. The goal is to encourage safe activity and exercise to maintain strength without overexertion that could lead to injury.
